A tdl carrihQgll is slidably mouhted'upon this; base The ros's slide 14,":1s shown in 2, is provided itha, nut 16 engaged by a ecie'x v 17 fotatably mounted 'Within the tool carriage 1 1 A -hand :wheel 18 on this screw 17 PermitS' itS rotatiohmd therefore pi'oideS trQnSVetSe movement for the "crdss slide Also, as shtvn gleai ly in Fig. 2

a ceh'tially disposed post 19is provided, the

jellfoss isliiie libeihg engaged by the outside surface of this 'post 19. Resting 611 this rcross slide l4 and surr011hdihg the eeiitralpost'l9 is the rotatable turret 20 having a circular way 21 extending about its lower surface. This is adapted to contact with a corresponding projection :l ornied centrally upon the upper surface of the cross slide l l.

This turret is surfaced to provide flat surfaces upon opposite sides on which may rest the tool supporting blocks Above the upper surface of the turret 20 are locle ing and clamping means 23 so that the turret may be rigidly clamped in position. As theselocking means and the clamping means may be similar to those now employed for these purposes they have not been specitlcally described or shown. To rotate the turret 20 to index the cutting tools the handle 2a is rotated, and to clamp or unclamp the turret 20 the handle 25 is rotated.

The supports on which are mounted the cutting tools 26 comprise removable blocks 22 positioned on opposite sides of the turret 20 so that the cutting tools 26 may be removed from the turret 20 while on the blocks 22. Other blocks 22 previously titted with tools may then be positioned in their place. Attached to the lower surfaces of the blocks 22 are bearing plates so that these plates 35 are removable with the blocks 22. The bearing plates 35 engage horizontal surfaces formed directly on the turret 20 and are forced by their clamping means against vertical side walls of the turret 20. These removable blocks 22 are in the form of strips resting upon the upper surfaces of the bearing plates 35 and held in place by clamps 29 disposed near the ends of the strips 22 and engaging their upper surface. These clamps 29 are fastened to the rotating part of the turret20 by screws 30. To further aid in holding these removable parts 22 on the turret 20, pins 31 in the clamps 29 engage re cesses formed in the removable blocks 22.

The removable plates or blocks 22 on their outer and prefe'ably oblique surfaces are provided with recesses 32 into which the cutting tools 26 may be placed. These cutting tools 26 may be clamped adjustably to the removable block 22 by clamping screws 33 shown in Figs. 4: and 5. Preferably clamping washers 3% are provided under the heads of the screws fitting over the lateral projections ot' the cutting tools 26. One of these screws 33 and washers ad; is provided on each side of the individual cutting tools 26.

It will be seen from this construction of the cutting tools so and their retaining moved from the turret 20 when the tools a as become dulled and require re-sharpening or dressing. ting tools 26, it is only necessary to grind oil aportion of their lat upper surfaces and,

for convenience, I preliminarily form each of the cutting tools 26 so that it W ll be in proper relative position to each of the other tools on the same block 22 for any specihed operation when the upper surfaces of each ing tools 26 simultaneously ground awa an In order to sharpen the cutequal amount so that their upper sur aces will remain in a common plane. If certain of the cutting tools wear more re idly than others, these may be adjusted slig tly to an elevated position before the grinding or sharpening ope 'ation.

What I claim is:
